Question

A boat traveling at 13.5 m/s relative to the water aims to go straight across a river. If the river is 150 m wide and the current in the river is 3.50 m/s, how far downstream will the boat land on the other side of the river? Calculate the answer in meters (m) and rounded to three significant figures.

Explanation / Answer

here,

speed of boat , vy = 13.5 m/s

width of river , w = 150 m

time taken to cross the river , t = w/vy = 150 /13.5 = 11.1 s

speed of river , vx = 3.5 m/s

the downstream the boat lands on other side , x = vx * t

x = 3.5 * 11.1 = 38.9 m
